The manager as per ID Act,1947 is completely different from present designation of manager is associated. The activity/works performed by the person in the establishment decides, whether he is a Manager, Supervisor or workmen. In my suggestion the aggrieved person should knock the door of law to challenge his/her termination or rights under the Act, after had a due consultation with any good lawyer. Trying is something better than leave fighting for justice. It is nice of Mr Sensharma to share a good information that "Remedy is available" one must search for that.
